Use mxDestroyArray to Release Memory for mxArray
The documentation for the mxSetCell, mxSetField, and mxSetFieldByNumber
functions in the MATLAB C and Fortran API incorrectly instructs customers to use
mxFree to release memory for any mxArray returned by mxGetCell, mxGetField, or
mxGetFieldByNumber.
Compatibility Considerations
The correct function to use to release memory for an mxArray is mxDestroyArray.
Calling mxFree on an mxArray only frees the array header, but does not actually free
the data itself and can result in a memory leak.
To help diagnose this problem, MATLAB issues a warning if calling mxFree on an
mxArray could cause memory corruption. In future versions of MATLAB, this condition
might result in a segmentation violation.
